How does a spectrum analyzer work?

February 14, 2025common problems 5760

A signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. While the information provided by the time domain (such as the rise and fall times of signal pulses) is important, the frequency domain allows you to determine the harmonic content of the signal, such as out-of-band emissions and distortion.

What is the difference between an arbitrary waveform generator and a function generator?

The Function Generator provides a preset list of waveforms or code patterns that it can generate. In a function generator, the user can change waveform parameters such as frequency, amplitude, and offset, as well as add simple distortion. Arbitrary waveform generators are more complex and can emulate real-world signals. Arbitrary waveform generators utilize pre-stored digital data to generate these waveforms,...

Clamp Meter Usage

If you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...

What is ATE System Power?
February 14, 2025 585
Automated Test Equipment (ATE) system power supplies are programmable power supplies designed specifically for ATE systems. Form factor is critical. ATE power supplies with higher power densities take up less rack space, reducing the factory floor space required for test equipment. The ATE power supply is a programmable power supply designed specifically for ATE systems.

What can a signal analyzer do?
February 14, 2025 588
Signal analyzers are capable of measuring the amplitude and phase of an input signal at a single frequency. The Signal Analyzer combines the large dynamic range of a swept-tuned spectrum analyzer with the power of a Vector Signal Analyzer (VSA) to perform in-channel measurements, such as Error Vector Magnitude (EVM) measurements, which require both magnitude and phase information. The VSAs are available in a wide range of sizes and sizes.
